5-HTP from Griffonia simplicifolia seed | 60 capsules | Serotonin precursor | Evening formula | Made in USA
Some evenings the day does not end when work ends. The mood stays gray, the fuse stays short, and the wind-down never quite arrives. That is not a willpower problem — it is often chemistry running low after a long stretch of output.*
What 5-HTP is: 5-hydroxytryptophan is the direct precursor your body uses to make serotonin — the neurotransmitter at the center of mood and emotional well-being. Your body produces it naturally from tryptophan; supplementing skips a step and supports normal serotonin levels directly.*
Why it earns a place in the evening stack: serotonin is also the raw material for melatonin. Supporting normal serotonin levels in the evening is one of the cleanest, most direct ways to support both emotional balance and the natural transition toward rest — without sedatives.*
Pairs naturally with Magnesium Drift for the full nervous-system downshift.*
Ingredients: Calcium (as Calcium Carbonate), 5-Hydroxytryptophan (from Griffo via simplicifolia seed extract), Gelatin (capsule), Magnesium Stearate.
